41 CFR § 102-74.415 - What is the policy for posting and distributing materials?
All persons entering in or on Federal property are prohibited from -
(a) Distributing free samples of tobacco products in or around Federal buildings, as mandated by Section 636 of Public Law 104-52;
(b) Posting or affixing materials, such as pamphlets, handbills, or flyers, on bulletin boards or elsewhere on GSA-controlled property, except as authorized in § 102-74.410, or when these displays are conducted as part of authorized Government activities; and
(c) Distributing materials, such as pamphlets, handbills or flyers, unless conducted as part of authorized Government activities. This prohibition does not apply to public areas of the property as defined in § 102-71.20 of this chapter. However, any person or organization proposing to distribute materials in a public area under this section must first obtain a permit from the building manager as specified in subpart D of this part. Any such person or organization must distribute materials only in accordance with the provisions of subpart D of this part. Failure to comply with those provisions is a violation of these regulations.
